Improve footnote handling

- Footnotes separator rather than headline to get around i18n
- Warn on footnote redefinition
- Do not export footnote definitions at point of definition, only in the
  footnote section.
- Do not automatically exclude Footnotes section to get around possibly hiding
  other content of such a section - and i18n.
  The user has the choice of explicitly hiding the section via a :noexport:
  tag.

and some other refactoring

- normal footnote reference [fn:1] [fn:6]
- further references to the same footnote should not [fn:1] render duplicates in the footnote list
- inline footnotes are also supported via [fn:2:the inline footnote definition].
- Footnote definitions are not printed where they appear.
Rather, they are gathered and exported at the end of the document in the footnote section. [fn:4]
[fn:4] so this definition will not be at the end of this section in the exported document.
Rather, it will be somewhere down below in the footnotes section.
[fn:5] this definition will also not be exported here - not only that, it will be overwritten by a definition
of the same name later on in the document. That will log a warning but carry on nonetheless.
* Footnotes
Please note that the footnotes section is not automatically excluded from the export like in emacs. [fn:7]
[fn:1] https://www.example.com
- footnotes can contain *markup*
- and other elements

[fn:4] another unused footnote

[fn:5] another unused footnote (this definition overwrites the previous definition of =fn:5=)
[fn:6]
Footnotes break after two consecutive empty lines - just like paragraphs - see https://orgmode.org/worg/dev/org-syntax.html.
This shouldn't happen when the definition line and the line after that are empty.
[fn:7]
There's multiple reasons for that. Among others, doing so requires i18n (to recognize the section) and silently
hides content before and after the footnotes.
this is not part of [fn:7] anymore as there are 2 blank lines in between!
